Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517220, here are decompositions:

13 + 33517207 = 33517220
31 + 33517189 = 33517220
43 + 33517177 = 33517220
103 + 33517117 = 33517220
193 + 33517027 = 33517220
199 + 33517021 = 33517220
229 + 33516991 = 33517220
271 + 33516949 = 33517220

Showing the first eight; more decompositions exist.
